Answer:
3.17mol
Explanation:
moles of Na = m/M ; Where M - molar mass of Na which is 23
moles of Na = 73/23 =3.17mol
but from the eqn n(Na) : n(NaOH) = 2:2 = 1:1
: . moles of NaOH is also 3.17mol

The acceleration is equal to force divided by mass which would be 100 / 50 which is 2 m/s2
Explanation:
Given
mass (m) = 44 kg
velocity (v) = 31 m/s
Now
Kinetic energy
= 1/2 mv²
= 1/2 * 44 * 31²
= 0.5 * 44 * 961
= 21142 joule
