10Figure 2 represents two glass flasks, P and Q, connected via a tap. Flask Q (volume = 1.00 x 103 cm3) is filled with ammonia (NH3) at 102 kPa and 300 K. The tap is closed and there is a vacuum in flask P. (Gas constant R = 8.31 J K1 mol1) Flask Q Figure 2 Flask P Tap 0 5 Give your answer to the appropriate number of significant figures. . 1 Calculate the mass of ammonia in flask Q.
