How many moles of calcium carbonate `(CaCO_(3))` are present in `10 g` of the substance ? `(Ca = 40 u , C = 12 u, O = 16 u)`

Find number of oxygen atoms present in 100 mg of CaCO_3. (Atomic mass of Ca = 40 u, C = 12 u, O = 16 u)

A sample of calcium carbonate (CaCO_(3)) has the following percentage composition : Ca = 40 % C = 12 % , O = 48 % . If the law of constant proportions is true , then the weight of calcium in 4 g of a sample of calcium carbonate from another source will be

What is the mass of 5 moles of sodium carbonate (Na_(2)CO_(3)) ? (Atomic masses : Na = 32 u , C = 12 u , O = 16 u )

Calculate the formula mass of sodium carbonate (Na_(2)CO_(3)) . (Given : Atomic masses : Na = 23 u, C = 12 u, O= 16 u )

How many moles are represented by 100 g of glucose. C_(6)H_(12)O_(6) ? (C = 12 u , H = 1 u , O = 16 u)

Calculate the formula mass of potassium carbonate (K_(2)CO_(3)) (Given : Atomic masses : K = 39u , C = 12 u , O = 16 u )

Complete the statement - One gram of calcium carbonate represents moles of the compound. [Ca=40, O=16, C=12]
