Question

A solution contain 30g of glucose ,20g of salt in 500ml of water calculate the mass of percent glucose , salt (density of water 1g/ml)
ans:The solution contain 30g glucose , 20 g salt and 500g water(density of water = 1g/ml so 500ml= 500g)
Total weight of solution by mass = 30g + 20g + 500 g = 550g
Mass % of glucose = 30/ 550 *100 = 5.45 %
Mass % of salt = 20 /550 *100 = 3.63%

Answer 1

Answer:

here is your answer

Explanation:

The solution contain 30g glucose , 20 g salt and 500g water(density of water = 1g/ml so 500ml= 500g)

Total weight of solution by mass = 30g + 20g + 500 g = 550g

Mass % of glucose = 30/ 550 *100 = 5.45 %

Mass % of salt = 20 /550 *100 = 3.63%

Answer 2

Given:

A solution contains $30g$ glucose and $20g$ salt in $500ml$ water

To find:

To calculate the mass of percent glucose and salt

Explanation:

• Here we are given different weights of different solutions.
• Mass refers to the quantitative measure. It measures the resistance to the acceleration.
• We can find this by adding the weights and then dividing them with the weights of the solutions given.

Solution:

The Density of water =  $1g/ml$

Now, Total weights:

$30g + 20g + 500ml\\\\= 550g$

Mass percentage of glucose:

$= \frac{30}{550} *100\\\\=\frac{3000}{550}\\\\= 5.45 %$

Mass percentage of salt:

$\frac{20}{550} *100\\\\=\frac{2000}{550}\\\\=3.63 %$

Hence, the mass percentage of glucose and salt is $5.45$ and $3.63$ respectively.
