439.3 g CO2

Explanation:

First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:

3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)

= 9.981 mol CO2

Use the molar mass of CO2 to determine the # of grams of CO2:

9.981 mol CO2 x (44.01 g CO2/1 mol CO2)

= 439.3 g CO2

What is the mass of a titanium alloy that has a heat of fusion of 422.5 joules/gram and requires 2,960 joules of energy to melt
romanna [79]

Answer:- Mass of the titanium alloy is 7.01 g, choice C is correct.

Solution:- The heat of fusion is given as 422.5 joules per gram and it also says that 2960 joules of heat is required to melt the metal completely.

The suggested equation is, Q=mH_f

where Q is the heat energy, m is the mass and Hf is the heat of fusion.

Since, we are asked to calculate the mass, the equation could be written as:

m=\frac{Q}{H_f}

Let's plug in the values in it:

m=\frac{2960J}{\frac{422.5J}{g}}

m = 7.01 g

So, the mass of the titanium alloy is 7.01 g, choice C is correct.
