Mass x SH x °C (or K) ΔT

= 75g x 0.45J/g/K x 6.0 ΔT

= 202.5 Joules of heat absorbed.

(202.5J / 4.184J/cal = 48.4 calories).

I guess that is the answer

Hello friend ☺

ΔH = MCΔT

ΔH = to the amount of energy or change in energy (J)

M = mass of substance

C = waters specific heat capacity

ΔT = change in temperature

and so ΔH = 75.20 * 4.18 * ( 28-22 ) = 1886.016 J

Thanks ❤

Add these measurements, using significant digit rules:<br><br> 1.0090 cm + 0.02 cm = cm

marin [14]

Answer:

1.029

Explanation:

1.0090 can also be looked at as "1.009"

0.02 can also be looked at as "0.020"

I think of it as 20+9 which is 29. There for your answer should be 1.029. There are no measurement rules applying to this equation since they are both in centimeters. So you don't have to convert anything.
