Question

Ile waży

a) 10moli H3PO4

b)0,1 kilomola MaOH

c)100milimoli C6H12O6

d) 10 kilomoli H3PO4

Answer 1

a)

 

M (H3PO4) = 98g/mol

10moli·98g/mol=980g

 

b)

 

M (NaOH) = 40g/mol

100moli·40g/mol=4000g=4kg

 

c)

 

M (C6H12O6) = 180g/mol

0,1mola·180g/mol=18g

 

d)

 

M (H3PO4) = 98g/mol

10000moli·98g/mol=980000g=980kg
