Answer:
47.5 mL
Solving:
M1 = 4.00 M
V1 = ?
M2 = 0.760 M
V2 = 0.250 L
---
M1 * V1 = M2 * V2
V1 = ( M2 * V2 ) / M1
V1 = ( 0.760 * 0.250 ) / 4.00
V1 = ( 0.190 ) / 4.00
V1 = 0.0475 L

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.
Answer:
21.4 M
Explanation:
7.5 mole / ( 350/1000) = 21.4 M
