The correct answer for the simple machine is, Lever
<u>Answer:</u> The moles of KHP in the sample is
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of KHP = 0.2000 g
Molar mass of KHP = 204.22 g/mol
Putting values in above equation, we get:
Hence, the moles of KHP in the sample is
<span>The coorrect answer is option A. The pressure of the gas can cause the ideal gas constant R, to take dfferent values. Because all the other three factors namely, Temperature (T), Volume(V) and the number of moles (n) can change the pressure of a gas. So, I f we change the pressure of the gas alone, we can change its gas constant R value.</span>
