Sand is not a compound and haven't a molar mass; also different types of sand exist.
200
(0.102gx1mole)/99g CuCl = 1.031x10^-3 moles
Multiply it by molecular mass.It is about 3400g
For this you need the atomic (molecular) mass of FeCl3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. FeCl3=162.4 grams .200 moles FeCl3
by vibration screen or mesh like 200#
200 grains = about 12.959 grams.
200/1000 x 6 = 1.2 moles
5
200g times 342.2965 g/mol = 68459.3 moles
200
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
20
g 1/200
So molarity means moles per litre. but you don't have a litre. if you did you'd have 1000/200 times the moles that you have. 2 moles / 200 x 1000 is 10 moles. As it is per litre, it is 2 molar.
200, it's all the same.
(0.102gx1mole)/99g CuCl = 1.031x10^-3 moles
