a)
1 mol -----56g
2 mln mol--------x
x=112 tony
b)
0,2 kilomola=200moli
1 mol ----- 98g
200moli------x
x=19,6 tony
c)
0,1 mili mola=0,0001 mola
1 mol -----28g
0,0001mola-----x
x=0,0028 g
d)
10 kilomoli = 10 000 moli
1 mol-------32g
10 000moli -------x
x=32 kg
e)
0,5 milimoli = 0,0005 moli
1 mol ------- 12g
0,0005 moli-----x
x=0,006g
f)
0,001 kilomola = 1 mol
1mol------56g
1------x
x=56g
a) MKOH=39g/mol+16g+mol+1g/mol=56g/mol
56g/mol * 2000000 = 112000000g = 112000kg = 112ton
