The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

How many moles of oxygen atoms are there in 9.0 grams of water?

Water has 18 grams per mole so 9 grams is 0.5 moles of water. There are 6.022* 10^23 molecules in a mole. Each water molecule contains *one* oxygen and *two* hydrogens.

How many oxygen atoms are in 3 moles of water?

Explanation: A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles so there are 3×6.022×1023 oxygen molecules .

How many atoms of oxygen are present in 1 mole of water?

Therefore there will be 6.022×1023 oxygen atoms in 1 mole or 18 g of water.

How many atoms of oxygen are in water?

one atom

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.

Answer: In 3 molecules of (H2O) 9 atoms of oxygen are present.

How many atoms are in 18 grams of water?

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 there in water?

three atoms

A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.

How many atoms are in 5g of H2O?

Water consists of two hydrogen atoms connected to one oxygen atom therefore molecular mass of water (M) is equal to sum of molecular masses of oxygen and two hydrogen atoms which is 2×1. 01 +15.99. Therefore molecular mass of water (M) is equal to 18 01. So in 5g sample of water there is 1.67 x 1023 water molecules.

How many atoms are in 10g of H2O?

18 g of H2O contains = 6.022×1023 molecules. 10 g of H2O cotains =6.022×102318×10 = 3.34×1023 molecules.
