Question

hello eveyone,
Can someone be so kind to explain what does 1000mL of a 7%s olution mean

Answer 1

7% by mass or by volume or by mole?

Answer 2

I'll assume it is by volume since a volume is given

Answer 3

7% tells you that for every 100L of solution, there are 7L of solute .

Answer 4

I think you can assume by volume

Answer 7

is it 70

Answer 8

Right

Answer 9
