Glucose has a molar mass of 180. There are thus 0.1 moles present in 18 g. 1 mole contains 6.022 x 1023 molecules. 0.1 moles contains 6.022 x 1022 molecules and so glucose with 24 atoms per molecule contains 24 x 6.022 x 1022 = 1.44528 x 1024 atoms.
360 g H2O x 1 mol/18g H2O x 6.02x10^23 H2O molecules/mol x 2 H atoms/molecule = 2.4x10^25 hydrogen atoms.
18g
Phthalic acid will dissolve 18g of per 100mL of boiling water. (25g/18g) x 100mL = 138.89mL of boiling water is needed to dissolve 25g of phthalic acid.
For this you need the atomic (molecular) mass of H2O. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. H2O= 18.0 grams2.5 moles H2O × (18.0 grams) = 45.0 grams H2O
Firstly, the moles of sufluric acid: n=? n=m/Mm=18g = (18)/(98.086)M=98.086 =.18molThefore, there is .18mol per 2 litre (18g in 2L)Therefore, its molarity is .09mol/L

360 g H2O x 1 mol/18g H2O x 6.02x10^23 H2O molecules/mol x 2 H atoms/molecule = 2.4x10^25 hydrogen atoms.
18g
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
glucose 1 mole has 180,156 grams and has 6.022 x 1023 atoms carbon 1 mole has 12,01 grams and has 6.022 x 1023 atoms. There are 6 carbon atoms in a glucose molecule so that times six would give you a total of 72,06 grams out of the 180,156. Carbon makes up about 40 percent of the total glucose mass so the final answer would be it would be around 2.4088 x 1023 atoms of carbon in one gram of glucose.
