You asked: How many moles are in 50g of Caco3?

100g Caco3=1mole.. , 50g of caco3=1÷100×50=0.5 mol..

How many moles are there in 50g of CaCO3?

∴ 50 g of CaCO3 = (1100×50) ( 1 100 × 50 ) mole = 0.5 mole.

How many moles are in 50 g of calcium?

Calculate the number of moles present in the following : (a) 50 g of calcium chloride. =0.450 moles.

How many moles are in 10g of CaCO3?

Therefore, number of moles in 10g of calcium carbonate is 0.1.

How many moles are in 100 g of CaCO3?

Gram molar mass of CaCO3 is 100 g. So, 100 g CaCO3 contains 1 mole of it.

How many moles are in 50g of NaCl?

We do this by looking up the relative atomic masses of Na and Cl in the periodic table. Na has an atomic mass of 23 and Cl is 35.5. So the Mr(NaCl)= 23 + 35.5 = 58.5. Putting all of this into our moles equation gives us the answer: moles= 50/58.5 = 0.855 moles (3sf).

What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
