An average quality lawn captures 4 times the carbon output of a typical gasoline-powered mower.
Answer: it would be 0.026 moles
Explanation: PV=nRT, P is the pressure of gas, V is the volume it occupies n is the number of moles of gas present in the sample, R is the universal gas constant which is equal to 0.0821 atm L/mol K and T is the absolute temperature of the gas
Answer:
<h3>The answer is 756 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of silver = 72 cm³
density = 10.5 g/cm³
We have
mass = 10.5 × 72
We have the final answer as
<h3>756 g</h3>
Hope this helps you
