eat for energy
Explanation:
plants eat the sugar for energy
Carbon, hydrogen should be the answer
Molality = moles Pb(NO3)2/ Kg H2O
373.5 g Pb(NO3)2 X (1 mole/ 331.2 grams)= 1.13 moles Pb(NO3)2
2.00 x 10^3 g (1 Kg/ 1000g)= 2 Kg
Molality= 1.13 moles/ 2 Kg= 0.565 molal.
Answer:
Mass of water = 41.8 g
Explanation:
Given data:
Mass of water = ?
Change in temperature = 3.0 °C
Specific heat capacity = 4.184 j/g.°C
Heat absorbed = 525 j
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 3.0°C
Now we will put the values in formula.
525 J = m × 4.184 j/g.°C × 3.0°C
525 J = m × 12.552 j/g
m = 525 J/ 12.552 j/g
m = 41.8 g
