To make a standard solution Apparatus: Volumetric flask Method: 1) 2.4g to 2.5g of sulphamic acid was weighed out‚ firstly by weighing the container and the sulphamic acid together‚ then pouring the sulphamic acid into a beaker. The container was then weighed again and the initial weight and the weight of the container alone were subtracted from one another to provide the mass of the sulphamic acid. 2) The sulphamic acid was then dissolved in 50cm³ of distilled water‚ using a glass

Determining the Density of Plastics 1) Introduction ⦁ a) Purpose: Determine density of different plastics ⦁ b) Hypothesis: If density is related to the ratio of mass to volume‚ then density can be calculated by using the formula D=M/V. i. c) Background: Density is the physical property that can be used to help identify substances. D=M/V. mass= found using a balanc and labeled in grams and volume=graduated cylinder or taking ( lxwxh ) measured in mL or cm3 2) Materials ⦁ a) List -graduated

Lab 34-2: 1. The general trend for bone density as a person ages is a steady decline as years pass. This study shows that every decade‚ males and females bone density slowly decreases. 2. Between the ages of 20-50 females lose about 11% of their bone density and males lose about 13% of their bone density. Males do in fact lose more density then females but they lose it at a more stable and steady rate. Females lose less density at more unstable rate going from about 6% (40-50) to about 9%

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

for Boost Juice experiencing economies of scale 1 – Purchasing inputs and raw materials in bulk • Buying in bulk means that the average cost of each unit of raw material is cheaper than if each unit was bought individually • In one year alone‚ Boost juice goes through more than 35 tonnes of mangos and you still have all of the other range of fruits that are bought. Therefore buying in bulk means that the average cost of the raw material decreases which therefore‚ using the value chain

EXECUTIVE SUMMARY: DAIRY INDUSTRY IN INDIA - AN OVERVIEW: Dairy enterprise is an important occupation of farmers. In India nearly 70% of the people depend on agriculture. It is the backbone of India. Dairy is linked with agriculture industry to a large extent. Animal husbandry in India is an essential part of agriculture. It is mainly a rural occupation closely associated with agriculture. In 1965‚ National Dairy Development Board [NDDB] was set up with the objective of meeting the demand

lifted and stowed in the holds of ships. As the time passed by‚ the concept of containerization emerged. Basically‚ Containerization is an inter-modal system of transporting the general cargo or product in lots which are too small for the traditional bulk transport system‚ using ISO standard containers that can be loaded and sealed intact onto container ships‚ railroad cars‚ planes‚ and trucks. The concept of containerization is considered as the key innovation in the field of logistics which has revolutionized
