dividing them by 3.The volumes of the two shapes substances were determined by using a graduated cylinder and a beaker. The first method that we used was the water displacement. The first sold substance was in a regular shape‚ and we calculated its mass by putting it on a balance 3 times. Next‚ we wanted to calculate the volume of the substance‚ so

Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time‚ and volume are measured by this system. There are many different techniques to measure all of the metric system. Length is measured

number of cells per unit volume of liquid”. For example‚ they might want to find out the density of red blood cells in blood plasma‚ the density of bacteria in milk‚ or the population of Paramecium sp. (a protozoan) in water from a pond. The simplest‚ most convenient and cheapest means of accurately determining the number of cells in a sample is to use a haemocytometer and a microscope. A haemocytometer is a specialised slide that has a counting chamber with a known volume of liquid. The haemocytometer

colourless. This process is known as decolourization. Thus‚ we can estimate the amount of Vitamin C in the brands of orange juice by comparing: 1.) The volume of vitamin C solution (of 0.1% concentration) needed to decolourize a certain volume of DCPIP solution. 2.) The volume of a certain brand of orange juice needed to decolourize the same volume of a known concentration of DCPIP solution. 3.)

Egg Buoyancy and Density: Can you make an egg float by changing the density of water? If you put an egg in tap water‚ it will sink to the bottom. If you add enough salt‚ the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone can do

Based on that the tank is a sphere-shaped and we have to find the volume‚ I used the formula for the sphere volume which is: V= 4/3(3.14 x r^3) V= 4/3(3.14 x 70^3) V= 4/3(1‚077‚020) V= 1‚436‚026.66666... V= 1‚436‚027 But I have to find the volume of the quarter sphere-shaped‚ so: V= 1/4 x 1‚436‚027 V= 359‚007 The volume of the quarter-shaped tank is 359‚007 cubic feet Holding Tank Calculations- 2.
