​

Answer 1

Answer:

nice question beady

Explanation:

100+0.5

100.5

0.5/100

Answer 2

Answer:

500ml

Explanation:

The volume of water to be added to 100ml of 0.5 M NaCl to get decimolar concentration.

100 ml of 0.5 M Nacl contains 0.05 moles of Nacl.

$\bold{\boxed{Number\: of\: moles(n)=\frac{MV}{1000}}}$

hence,

$Number\: of\: moles=\frac{0.5×100}{1000}$

$Number\: of\: moles=0.05$

Decimolar solution means 0.1M.

$\bold{\boxed{Volume(V)=\frac{n}{M}}}$

$V=\frac{0.05}{0.1}$

$V=500ml$
