Question

a solution contains 5 gram of glucose and 45 gram of of H2O calculate the concentration of solution in mass percentage​

Answer 1

Answer:

The concentration of the solution in mass percentage is $10$$%$$%$%·

Explanation:

The mass percentage is used to express the concentration of solution when the mass of solute and solution are given·

Here,

 mass of solute, glucose $= 5g$

 mass of solvent,  $H_{2} O = 45g$

 mass of solution         $=$  $5g + 45g = 50g$

We know,

    mass percentage  $= \frac{mass of solute }{mass of solution}$   ×   $100$

∴ mass percentage of the solution    $= \frac{5g}{5g + 45g}$  × $100$

⇒   mass percentage of the solution $= \frac{5}{50}$  ×  $100$

⇒   mass percentage of the solution $= 10%$%

Answer 2

EXPLANATION

5+45=50

we had to find mass

mass=weight ÷ gravity

there is no gravity in this question

So,mass=50÷1

mass = 50

in percent

=50/100

=50×1/50×2

=1/2

FINAL ANSWER

1/2

in decimal form

=0.5
