Answer:
To make 500 mL of a solution of PPP 1% w/v you need 5g
Explanation:
A percent w/v solution is calculated with the following formula using the gram as the base measure of weight (w):
% w/v = g of solute/ mL of solution × 100
A 1% w/v means that you have 1 g of PPP per 100 mL of solution
Thus, if you need to make 500 mL of solution you will need 5 g of PPP.
I hope it helps!
Answer:
ΔT = 20.06 °C
Explanation:
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 1.17 kJ = 1170 J
m = mass = 24.1 g
Cp = Specific Heat Capacity = 2.42 J.g⁻¹.°C⁻¹
ΔT = Change in Temperature = <u>??</u>
Solving eq. 1 for ΔT,
ΔT = Q / m Cp
Putting values,
ΔT = 1170 J / 24.1 g × 2.42 J.g⁻¹.°C⁻¹
ΔT = 20.06 °C
I don’t really know this but I think
