Answer:

2.5litres

0.0005moles

0.56M

0.75M

0.1369M

0.255moles

0.0163M

0.10625M

3.312g

1221.14cm³

Explanations

1. 25÷1000=2.5l

2.Moles=Mass÷RFM

50÷1000÷(100)

0.0005moles

3.I litre=1000cm³

0.75litres=?

750cm³

0.42moles=750cm³

?=1000cm³

0.56M

4. Molarity=Conc. in g/l÷RFM

Conc.g/l

15g=500cm³

1000cm³

30g/l

Molarity

30÷(23+16+1)

0.75M

5.4.6g=250cm³

1000cm³

18.4g/l

Molarity

18.4÷(134.446)

0.1369M

6.3moles=1000cm³

(0.085×1000)

0.255moles

7.Conc.g/l

37.5cm³=0.181g

1000cm³

4.827g/l

Molarity=4.827÷(296)

0.0163M
