What you need to do is find the Molar mass of sodium and then divide your mass (0.25g) by the molar mass of Na. 

Therefore   0.25g/22.9898g/mol (do you see how the "grams" unit will cancel out? That will leave you with the number of moles you have.

A cable raises a mass of 158.0 kg with an acceleration of 1.8 m/s2. What force (in N) of tension is in the cable?
ki77a [65]

Answer:

Force of Tension = 1832.8  N

Explanation:

Any mass of object supported or pulled by a rope or cable  is subject to a force of tension. Since the mass is raised by a cable, tension is involved.

Mathematically,

Tension = mass × gravity(9.8 m/s²)

Tension can be represented as

T = (m × g) + (m × a)

Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.

mass = 158 kg

a = 1.8 m/s²

g = 9.8 m/s²

T = mg + ma

T = m(g + a)

T = 158(9.8 + 1.8)

T = 158 × 11.6

T = 1832.8  N
