Answer:

Explanation:

Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle

torque is zero as , centripetal force passes through axis of rotation that is center.

So work done by centripetal force  = 0

So work done by tension on M = 0

How many liters are in 0.034 moles of chlorine gas?
Anuta_ua [19.1K]

The volume of the gas is 7.6\cdot 10^{-4}m^3

Explanation:

At standard temperature and pressure (stp), the volume occupied by 1 mole of an ideal gas is always equal to

V=22.4 L

In this problem, we have an amount of moles of gas of

n = 0.034 mol

Since 1 mol of gas occupies a volume of 22.4 L, we can set up the following ratio:

\frac{1 mol}{22.4 L}=\frac{0.034 mol}{V}

where V is the volume occupied by 0.034 mol of gas. Solving for V, we find

V=\frac{0.034 mol}{1 mol}(22.4 L)=0.76 L

Or, in cubic metres,

V=0.76 L = 7.6\cdot 10^{-4}m^3
