What you would want to do here is dividing mass by density. In fact, density is referred to as a ratio of mass to volume. There is no need for any unit conversion as they are already comparable. So the result should be 105g / 11.3g/ml =9.3ml.
English is not my first language, so sorry for language issues of any kind.

Answer:
The methane gas burns
Explanation:
The burning of methane gas is a combustion reaction. Combustion is an exothermic process. For all exothermic processes, ∆H is negative.
Combustion reaction involves the evolution of heat. The energy of reactants is greater than the energy of products hence the excess energy is given off in the form of heat leading to a negative value of the enthalpy of reaction, hence the answer.
Answer:
15.38 g is the mass for M in the 329 g of sample
Explanation:
Mineral's formula: MS
Our sample weighs 44.9 g
Mass of M: 2.1 g
Our new sample weighs 329 g
We may solve this by a rule of three:
44.9 g of sample contain 2.1 g of M
329 g of sample will contain (329 . 2.1) / 44.9 = 15.38 g
