Explanation:
According to the given situation the calculation of grams of PbO and grams of NaCL is shown below:-
Moles of Pb(OH)CL is
= 0.0385 mol
Mass of PbO needed is
After solving the above equation we will get
= 8.59 g
Mass of NaCL needed is
After solving the above equation we will get
= 2.25 g
Therefore we have applied the above formula.
Answer:
Given - acc = 4 m/ s^2
Force = 255 N
To find = mass
Solution -
Using the formula,
255 = Mass × 4
255 /4 = Mass
63.75 = Mass
1 N = kg m/s^2
63.75 kg = Mass
