Answer:
Mass of solvent is 1127.3 g
Explanation:
NaOCl → 3.62%
This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:
100 g of bleach solution have 3.62 g
1169.6 g of bleach solution may have (1169.6 . 3.62) /100 = 42.3 g
42.3 g is the mass of NaOCl in the solution
Mass of solution = Mass of solvent + Mass of solute
1169.6 g = Mass of solvent + 42.3 g
1169.6 g - 42.3 g = Mass of solvent → 1127.3 g

<h2>Work done = mgh </h2>
Explanation:
- In this case, while lifting the book we are working against the force of gravity.
Using the Newton's laws, we can find the force F required for lifting the book having mass (m) and acceleration due to gravity (g) that is ;
and, the change in the position of the book that is Δx (Height)
→ Δx = Final position - Initial position
which is only the height, then the amount of work done will be calculated by :
W= mgh
m = Mass of the Body
g = Acceleration due to Gravity
h = Height of Body being displaced
The specific heat capacity the substance is calculated using the below formula
Q(heat) = Mc delta T
Q =1560 cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?
by making c the subject of the formula
c=Q/m delta T
= 1560 cal/ 312g x 15 c = 0.33 cal/g/c (answer B)
