Hello!
the atomic mass of one atom of hydrogen is equal to 1.00784 in atomic mass units
one atomic mass unit is equal to 3.6609e-27 pounds
which means one atom of hydrogen is equal to 3.9478732e-27 pounds
I hope this helps, and have a nice day!
We are given with two set of conditions. To calculate the final volume, we get first the number of moles under the first condition. Using PV=nRT, the number of moles is equal to 0.16 moles. We substitute this together with the other conditions in PV=nRT, the final volume is 0.92 liters.
The relative atomic mass of the element is 15.99 and the element is oxygen.
<h3>What is the relative atomic mass of the element?</h3>
Let us note that owing to the fact that elements often have isotopes, the relative atomic mass is not always a whole number. Now we have tp obtain the relative atomic mas from the atomic masses of the elements.
Thus;
X = (15.99 * 0.99762) + (16.999 * 0.00038) + (17.999 * 0.002)
X = 15.95 + 0.0065 + 0.036
X= 15.99
Thus the relative atomic mass of the element is 15.99 and the element is oxygen.

When an iron object is left in damp air for a considerable time, it gets covered with a reddish- brown flaky substance called rust. ... Rusting of iron is a chemical change because a new substance iron oxide is formed. The presence of oxygen and water or water vapour is essential for rusting.
