How many moles of methane (CH4) are in 7.31 x 10^25 molecules
Ivan

molar mass of methane CH4

= C + 4 H  

= 12.0 + 4 x 1.008

= 12.0 +  4.032

= 16.042g/mol

7.31 x 10^25 molecules x <u>             1 mole  CH4    </u>  = 121.43 moles

                                       6.02 x 10^23 CH4 molecules

121.43 moles CH4 are present.

A zinc block with a mass of 230 g is given 1320 J of energy. What is the change in
Mariana [72]

Answer:

14.7°C

Explanation:

Q = m·ΔT·c

ΔT = \frac{Q}{m*c}

ΔT =\frac{1320 J}{230 g* 0.39 J/gC}

     = 1320 J / ((230 g) * (.39 J/g°C)

ΔT = 14.7 °C
