Answer:
1088.89 Pa
Explanation:
According to the Newton's second law of motion:-
Mass = 50.0 kg
Acceleration = g = 9.81 m/s²
So,
Force = 490 N
Area of the base =
=
m² = 0.45 m²
<u>Pressure = Force/Area =
= 1088.89 Pa</u>
Answer:
13.2 g Na2CO3
Explanation:
Convert 10.0 g NaOH to mol.
10.0 g x 1 mol/39.997 g = 0.250 mol
Use mol ration given by the equation: 2 mol NaOH to 1 mol Na2CO3
0.250 mol NaOH x 1 mol Na2CO3/2 mol NaOH = 0.125 mol Na2CO3
Finally, convert the moles of Na2CO3 to grams.
0.125 mol Na2CO3 x 105.99 g/1 mol = 13.2 g
Given a mole each for iron and magnesium, the number of atoms of each element is equal. Iron has a greater mass due to its greater molecular weight. The correct statement among the choices is D.
