A 9.35 gram of ring with it's volume of 0.654 cm3 is an alloy of gold and with density of gold and silver respectively 19.3 g/cm3 and 10.5 g/cm3 assume there is no change in volume when pure metals are mixed. The volume of gold is?

To find the volume of gold in the alloy, we need to first determine the total volume of the alloy. Here's how we can do it step by step:
Step 1: Calculate the total mass of the alloy
The given mass of the ring is 9.35 grams.
Step 2: Determine the total volume of the alloy
The given volume of the ring is 0.654 cm³.
Now, since we are assuming no change in volume when metals are mixed, we can conclude that the total volume of the alloy is equal to the volume of gold plus the volume of silver. We can set up the following equation:
Volume of gold + Volume of silver = Total volume of the alloy
Let's solve for the volume of gold:
Step 3: Find the mass of gold
Since gold is part of the alloy, we can find its mass using the following formula:
Mass of gold = Total mass of the alloy × (Percentage of gold / 100)
The percentage of gold is not given in the problem, so we need further information to determine it.
