Question

What is the number of moles for these three questions?

The apparatus shown consists of three temperature-jacketed 1.520 L bulbs connected by stopcocks Bulb A contains a mixture of H2O(9). CO2(g), and N2(g) at 25°C and a total pressure of 558 mm Hg Bulb B is empty and is held at a temperature of -70°C Bulb Cis also empty and is held at a temperature of -190°C. The stopcocks are closed, and the volume of the lines connecting the bulbs is zero CO2 sublimes at-78°C, and N, boils at -196°C (Figure 1) Figure < 1 of 1 > 25 °C -70 °C -190 °C

these are the previous parts:
