Find the mass of 4.5 moles of H3PO4
Contact [7]

Hey there!

H₃PO₄

Find molar mass.

H: 3 x 1.008 = 3.024

P: 1 x 30.97 = 30.97

O: 4 x 16 = 64

---------------------------------

                  97.994 grams

The mass of 1 mole of H₃PO₄ is 97.994 grams.

We have 4.5 moles.

97.994 x 4.5 = 440

The mass of 4.5 moles of H₃PO₄ is 440 grams.

Hope this helps!

Which statement correctly compares electric charge with electric current?
Arisa [49]

Answer:

Your answer would be D) They both require a movement of charged particles

Explanation:

In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use

                              ~Notify me if you have questions~

                              Have a nice day and hope it helps!

A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma) 3.5 N 115 N 165 N 4.5
Ksju [112]
<h3>Answer:</h3>

3.5 Newton

<h3>Explanation:</h3>

We are given;

Mass of the ball = 140 g

Acceleration = 25 m/s²

Required to find the force;

  • According to Newton's second law of motion, the resultant force on a body in motion and the rate of change in linear momentum are directly proportional.
  • That is; F \alpha \frac{Mv-Mu}{t}
  • Thus; F = ma , where F is the resultant force, m is the mass and a is the acceleration.

To get the force we substitute the value of m and a in the formula;

Therefore;

F = 0.14 kg × 25 m/s²

  = 3.5 N

Hence, the force needed to accelerate the ball is 3.5 N
