How many atoms are in 16 grams of methane?

Answer: 3.01 × 10^23 atoms. Explanation: The molar mass of methane is 16 g/mol.

How many atoms does 18 grams of water have?

The chemical formula of water is H2O, in water two mole of hydrogen is present and one mole of oxygen is present. So, in a single molecule of water, two mole of hydrogen are present. 18 g of water will contain ⇒1×12.046×1023=12.046×1023 atoms of hydrogen.

How many atoms are present in 18g of methane?

18g of mithane CH4. 18 g of CH4 has maximum number of atoms as CH4 contains five atoms .

How many moles of atoms are in 16 grams of methane?

16g methane (CH4) represent 1 mole and has 6.02×1023 molecules of methane.

How many moles of h2o are present in 18 gram of water?

1 mole
– We can say that 18 grams of water means same as 1 mole of water , and in this NA Avogadro number of water molecules are present , which means 6.02×1023 molecules.

How many hydrogen atoms are there in 16g of methane?

Use the unit-factor method (aka dimensional analysis) …. The Relative Atomic Mass of Carbon is 12, that of Hydrogen is 1. There are 6.02 x 10^23 (Avogadro’s Number) of methane (CH4) molecules in 16g (12g of C + 4x1g of H) of methane so there are 4/16 ie 1/4 of that in 4g of methane. That is, 1.50 x 10^23 carbon atoms.

Which has maximum number of atoms 18g of H2O?

Hence, 18 g of CH4 has maximum numbers of atoms.

How many atoms are in a gram of water?

1 mol C contains 6.022 × 1023 C atoms; its mass is 12.01 g. 1 mol O contains 6.022 × 1023 O atoms; its mass is 15.994 or 16.00 g. 1 mol Br contains 6.022 × 1023 Br atoms; its mass is 79.90 g….Number of Atoms in a Drop of Water.

Molecule	Molecular Weight	Mass of 1 Mol of Molecules
HgBr2	200.59 + 2(79.90) = 360.39	360.39 g

Which has a greater number of molecules 18 grams of h2o or 18 grams of CH4?

This means less will be the molecular mass, more will be the number of atoms. Hence, 18 g of CH4 has maximum numbers of atoms.

Which of the following has maximum number of atoms 18 gram of water 16 gram of oxygen?

16 g of CH4 has maximum number of atoms.

How many h2o molecules are in one mole of water?

6.02 × 10 23
The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

How many atoms of oxygen are there in 18 g of water?

– As in one mole of water there are6.022×1023 molecules, that’s how the mole was defined. – And as the chemical formula for water is H2O, and one mole of water corresponds to one mole of oxygen atoms. Hence, there will be 6.022×1023 oxygen atoms in one mole, or we can say 18 g of water.
