Answer:
D is the answer because I think it is right plus I know they don't use two off them
Umm i don’t get it, is it a joke?
58kg
Explanation:
Given parameters:
Mass of bicycle = 8kg
Total force exerted = 191.4N
Acceleration = 2.9m/s²
Unknown:
Naomi's mass = ?
Solution:
Force is a product of mass and acceleration as sated in the second law of newton.
Force = mass x acceleration
Total force on the bicycle = total mass x acceleration
191.4 = (8 + k) 2.9
8 + k =
= 66
K = 66 - 8 = 58kg

Molecular formula of sulfur trioxide is SO₃
Molar mass of SO₃ is - 32 + (16 x 3 ) = 80 g/mol
1 mol of any substance consists of 6.022 x 10²³ units. In 1 mol of SO₃ there are 6.022 x 10²³ molecules of SO₃
in 80 g of SO₃ - there are 6.022 x 10²³ molecules of SO₃
Therefore in 78 g of SO₃ - there are 6.022 x 10²³ /80 x 78 = 5.871 x 10²³ SO₃ molecules
