Question

some sugar dissolved in 150 gram of watar to make it 15% of consentration (by mass) calculate the mass of sugar​

Answer 1

Answer:

1000mg.

Explanation:

1000mg is the correct answer.

Answer 2

Explanation:

total mass of water = 150g

sugar dissolved = 15%

total mass = 150+ 15%

=

$\frac{150 \times 100}{1 \times 100} + \frac{15}{100}$

$\frac{15000 \: + 15}{100}$

Total % of the solution = 100% – 15%

= 85%

Total mass of sugar is = 150.15 – 85%

= 150.15 – 85/100

= 15015/100 – 85/100

= 15015 – 85 /100

= 14930 /100

= 149.30g
