Question

a nugget of gold and quartz weigh 100g. Specific gravity of gold, quartz and nuggets are provided... calculate weight of gold! plz refer to the image added​

Answer 1

Answer:

Since we know that volume is mass/ density . As by the given formulae we can calculate the densities of nugget, gold and quartz which will be 6.4, 19.3 and 2.6 respectively.

So, now let the weight of the gold be x gram so the weight of the quartz is (100-x)gram.

So weight will be (X/19.3) + (100-x /2.6) =(100/64). So, now on calculating we will get the weight of the gold to be 68.6 grams.

Answer 2

Answer:68.6g

Explanation:

First of all we have given the weight of nugget i.e 100g

So we can calculate by taking the weight of gold in nugget be x .

Then weight of quartz will become (100-x)

Now tabulate in the formula and solve.....
