Answer 1

Answer:

Hi mate Here's your Answer.

Step-by-step explanation:

1m = 1000mm

36m = 36,000mm

Hence 3.6mm = 0.0036m

Percentage = 0.0036 × 100 = 0.36%

Answer 2

$answer :$

$molarity \: of \: sulphuric \: acid \: = \: 3.6m$

$percentage \: by \: mass \: of \: H2SO4 \: in \: solution \: = \: 29℅$

$molar \: mass \: of \: H2SO4 \: = \: \frac{98 \: g}{mol}$

$using \: this \: formula :$

$molarity \: = \: percentage \: by \: mass \: \times \: 10 \: \times \frac{dnsity}{molar} mass \: of \: solute$

$or ,\: 3.6 \: = \: 29 \: \times \: 10 \: \times \frac{density \: of \: solution}{98}$

$or, \: 3.6 \: \times \frac{98}{290} \: = \: density \: of \: solution \:$

$hence, \: density \: of \: solution \: = \: 1.216 \frac{g}{ml}$
