True

Work Step by Step

Molar mass of $He$ is less than $Ne$. Therefore, number of moles of $He$ in 10.0g is greater than the number of moles of $Ne$ in 10.0g. Pressure is higher when there are more particles. Therefore, the statement that the flask containing $He$ has the higher pressure is true.
