350 calories of heat is added to a sample of nitrogen gas and the temperature is increased by 89 degrees Celsius. What is the mass of the nitrogen sample in cal/gram Celsius?

• chemistry -

Mass is measured in grams, not cal/gram celsius. Specific heat is measured in cal/g*C. .
q = mass x specific heat x delta T. Look up specific heat for N2 gas, substitute 89 for delta T and 350 cal for q1, calculate mass in grams.

• chemistry -

so if I am given the specific heat of 0.25 cal/g*C, then would my answer be
1.25 x 10^5 grams?

• chemistry -

Not on my calculator.
350 = mass x 0.25 x 89
mass = [350/(0.25*89)] = about 16 or so grams.
