I just want 24 and 26 GRAMSMOLESMOLESGRAMS CONVERSIONS Calcu

GRAMS-MOLESMOLES-GRAMS CONVERSIONS Calculate the number of grams in the following compounds. 23) 2 moles of CaSO,*2H,O 24) 0.50 moles of C12H20 25) 5 moles of SiO2 Convert from grams to moles in the following compounds. 26) 49.5 g of H,so, 27) 8.36 g of NaCIO,

Solution

Question 24

Molar mass of C12H22O11 is 342.2965 g/mol m

If you multiply moles with molecular weight then you will get number of grams

Mass of C12H22O11  = 0.5 mol x 342.2965 g/mol = 171.1483 gm

Question 26

Mass of H2SO4 = 49.5

Molar mass of H2SO4 is 98.0785 g/mol

Moles of H2SO4 = 49.5 / 98.0785 = 0.5046 Moles
