PLEASE HELP!! What is true about 1.0 mol Wand 1.0 mol He?
a
b

They have the same atomic mass.
They are equal in mass.
They contain the same number of atoms.
Their molar masses are equal.
C С

How have the greenhouse gasses increased from the year 2000 to 2018

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What are the chemical names of these compounds? ke: mg3n2: reset next
