The pressure of a gas is 100.0 kPa and its volume is 500.0 mL. If the volume increases to 1,000.0 mL, what is the new pressure o
elena-14-01-66 [18.8K]

Answer:

P_2=50kPa

Explanation:

Hello,

In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:

P_1V_1=P_2V_2

Next, we compute the final pressure P2:

P_2=\frac{P_1V_1}{V_2}=\frac{100.00kPa*500.0mL}{1000.0mL} \\\\P_2=50kPa

Thus we validate, the higher the volume the lower the pressure.

Best regards.

How many milliters of a 0.171 solution contains 1.00 g of NaCl
svet-max [94.6K]
:  <span> Molar mass of NaCl: 35.4+22.9 = 58.3 g/mol

X milliliters (=X/1000 liters) of a 0.171M solution contain 0.171*X/1000 moles of NaCl.
0.171*X/1000 moles of NaCl = 58.3*0.171*X/1000 g = 1 g (as given)
58.3*0.171*X/1000 = 1
X = 100.3 </span>
