6. What is the mass of the object if the net force acting on it was 356 N and the acceleration rate
Marina86 [1]

The mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.

<h3>How to calculate mass?</h3>

The mass of an object can be calculated using the following formula:

F = ma

Where;

  • F = force (N)
  • m = mass (kg)
  • a = acceleration (m/s²)

m = F/a

m = 356/4

m = 89kg

Therefore, the mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.

4.2g of sodium bicarbonate is equivalent to how many moles of sodium bicarbonate
Mnenie [13.5K]
<span>The mass of one mole of sodium bicarbonate (aka NaHCO3) is equal to 1 * 22.99g/mol + 1 * 1.00g/mol + 1 * 12.01g/mol + 3 * 16.00g/mol = 83.91g/mol. From this, we can convert 4.2g of NaHCO3 to moles by dividing by 83.91g/mol, to get 0.050 moles of sodium bicarbonate.</span>
