Explanation:
Make a table, listing the x and y coordinates of each square's center of gravity and its mass. Multiply the coordinates by the mass, add the results for each x and y, then divide by the total mass.
The x-coordinate of the center of gravity is 15/14 a.
The y-coordinate of the center of gravity is 47/42 a.
Answer:
1.636 x 10^-5 m^3
Explanation:
As we know that
1 mol of copper = 63.5 g of copper
2.3 mol of copper = 63.5 x 2.3 = 146.05 g of copper = 0.146 kg of copper
Density of copper = 8.92 x 10^3 kg/m^3
The relation between mass and volume is given by
mass = volume x density
Thus, the volume of copper is 1.636 x 10^-5 m^3.
