Answer:
d = 4.5 g/cm³
Metal cube is made up off titanium.
Explanation:
Given data:
Edge length of cube = a = 11.4 mm
Mass of metal cube = 6.67 g
Density and identity of metal = ?
Solution:
First of all we will calculate the volume of cube.
V = a³
V = (11.4mm)³
V = 1481.54 mm³
mm³ to cm³:
1481.54 mm³× 1 cm³/ 1000 mm³
1.482 cm³
Density:
d = m/v
d = 6.67 g/ 1.482 cm³
d = 4.5 g/cm³
Metal cube is made up off titanium because density of titanium is 4.5 g/cm³.
Im dying at the fact that you put in under ‘Chemistry’, good luck though.
The answer is carbon dioxide
Answer:
1) 1,8066*10^24 molecules of water
2)2,4088*10^24 atoms of carbon
3)4,8176*10^24 atoms of oxygen
4)2,6071*10^23 molecules og NaCl
5)107,221 g of calcium bromide
6)0,0814 moles iron III nitrate
Explanation:
You would add water to the mixture to dissolve the salt. When the salt is dissolved, you have your sand alone.
