How do you test vitamin c?
One common way to test for vitamin C is by using iodine solution. Ascorbic acid in vitamin C reduces iodine to iodide, causing the iodine solution to change color from brown to clear. Another method is using UV-visible spectrophotometry to measure the absorbance of vitamin C at a specific wavelength. Additionally, titration with an oxidizing agent such as iodine can also be used to determine the vitamin C content in a sample.
What is the CGS unit of pole strength?
Pole strength in SI is the Ampere-meter, A*m A = 10-1*c*Fr/s Fr = Franklins = g1/2cm3/2/s m = 102cm So in CGS, pole strength would have the following unit: 101cm5/2*g1/2*c/s2 where cm = centimeter, c = the speed of light, s = seconds and g =gram
How do you test an apple for vitamin C?
To test an apple for vitamin C, you can use an iodine test kit that changes color in the presence of ascorbic acid (vitamin C). Simply follow the kit's instructions to see if the apple contains vitamin C. Alternatively, you can juice the apple and use a vitamin C test strip to detect the presence of the vitamin in the juice.
What is the indicator for lipids?
One common indicator for lipids is the triglyceride level in the blood, which measures the amount of fats circulating in the bloodstream. High levels of triglycerides are associated with an increased risk of cardiovascular diseases.
What is the density of something with a mass of 21 grams and volume of 2 cm3?
Density = Mass/Volume = 21g/2cm3 = 10.5 grams per cm3
What is the density of a cube with a mass of 8 grams and a volume of 2 centimeters cubed?
Density = mass/volume Density of the cube = 8g/2cm3 = 4g/cm3
What is the density of 2cm3 sugar cube with a mass of 3.18?
Density = Mass/Volume = 3.18/2 = 1.59 grams per cm3
What is the density of an object with a mass of 60g an a volume of 2cm3?
30g/cm3
What is the density of an object with a mass of 60grams and a volume of 2cm3?
Density=M/V there's your answer... i am doing the same test...only i have about 10 questions...aw
What is the density of an object that is mass 15 g volume 2cm3?
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
A rectangular solid is 3 cm long 2 cm wide 1 cm mass is 12g What is its density?
What you do find the volume by multiplying the height the width and the length So... 3x2x1=6 Then you divide the mass by the volume m/v= 12 / 6 So... The answer is 2cm3
What is the density of a rock that has a mass of 6g and a volume of 2ml?
d=M/V where d:density M:mass V:volume we know that 1L=1000ml so 5ml=0.005l we have to convert 0.005ml into cube M .1L=1 cube dm so 0.005L=0.005 cube dm.1 cube m=1000 cube dm so 0.005 cube dm=5 cube m d=2g/5 cube m d=0.4g/cube m or d=2g/5ml d=0.4g/ml(d=0.4)
How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
How do you test the vitamin c in orange juice?
How to test for vitamin C: 1. Draw up 2cm3 of lemon/orange juice (or the substance you're wanting to test for vitamin C) into a syringe. 2. Add it drop by drop into 2cm3 of a 0.1% solution of DCIP (a blue dye) 3. The dye will turn colourless if vitamin C is present
How many grains of sugar are in a bag of sugar?
that's just like asking how many grains of sand are on a beach...... what you could do is... measure the size of a grain of sugar - width, length, height and times these together to find its volume. then empty a bag of sugar and fill it with water, until where the sugar reaches when filled. pour the water into a measuring jug - you now have the volume of sugar that the bag takes in cm3. the grains of sugar will have a few air spaces between them so take a rough guess at this amount - maybe 1-2cm3 now minus this from the volume of the bag. divide the volume of the bag by the volume of one grain of sugar. this will be an approximate figure of how many grains there are.
What is the surface to volume ratio of a cube that is 2 centimeters long on each side?
So your cube is 2cm3? Right, lets do some maths! Okay, so the surface area is taking your cube, and cutting along the edge to show a net of the cube. So the maths is: 2x2x6, the 2x2 because the square will be 2cm high by 2cm wide, the 6 becuase a cube has 6 sides. 2x2x6=24, so the answer for Surface Area is 24cm2. Now for the Volume, the volume is the width x length x depth, which is easy. 2x2x2= 8, so the answer for Volume is 8cm3. So the SA:V ratio is 24:8. Hope that helps!
