A wedding ring presented to a bride contains 788 mg of gold and the rest is diamond. If the ring weighs Ig the bride receives (At. mass Au = 197, C = 12)

Calculate the number of gold atoms in 300 mg of a gold ring of 20 carat gold (atomic mass of gold = 197, pure gold is 24 carat).

Number of moles of gold present in a piece of gold has a mass 12.6 g is (AU = 197)

A ring made of diamond and gold weighs 5gxxg in air and 4.6gxxg in water. The specific gravities of gold and diamond are 19.3 and 3.5 respectively. Determine the mass of diamond.

Calculate the number of gold atoms present in 0.450 g of a gold ring made from 22 carat gold. Given that the atomic mass of gold is 197 and pure gold is 24 carats.

The mass of precious stones is expressed in terms of ‘carat’. What is the mass of a ring in grams which contains 0.600 carat diamond and 8.500 g gold given that 1 carat = 3.168 grains and 1 g = 15.4 grains ?

A young has given his bride an engagement ringg containing 0.50 carat diamond. How many atoms of carbon is present iin that ring? [1 carat=200 mg].

A bride presents a 10 carat diamond ring to her groom during engagement. Calculate how many carbon atoms actually she gifted? [1 carat = 200mg]

The mass of precious stones is at present in terms of carat Given that 1 carat = 3.168 grains and 1 gram = 15.4 grains, calculate the total mass of the ring is grams and kilograms which contains 0.500 carat diamond and 7.00 gram gold.
