How many grams of a 32.9% potassium sulfate solution would contain 181.6 g potassium

Chemistry
1 answer:
Anna007 [38]3 years ago
8 0

Answer:

grams of solution = 551.98 g

Explanation:

Given data:

Percentage of solution = 32.9

Mass of solute = 181.6 g

Grams of solvent = ?

Solution:

Formula:

%  = [grams of solute / grams of solution] × 100

Now we will put the values in formula.

32.9 = [ 181.6 g / grams of solution] × 100

grams of solution = 181.6 g × 100 / 32.9

grams of solution = 18160 g /32.9

grams of solution = 551.98 g

In the following reaction, how many grams of silver can be produced from 49.1 g copper?

166.4 g Ag grams of silver can be produced from 49.1 g of copper.

<h3>What is a mole?</h3>

A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs.

1 mol Cu + 2 mol AgNO_3 → 2 mol Ag + 1 mol Cu(NO3)2

63.55 g Cu —> 2 x 107.688 g Ag

63.55 g Cu gives 215.376 g of Ag

So, 49.1 g Cu —> \frac{215.376 g X 49.1 g}{63.55 g}

= 166.4 g Ag

Hence, 166.4 g Ag grams of silver can be produced from 49.1 g of copper.

What is the kinetic energy in kJ of 1 mole of water molecules (mass=18) if the average velocity is 590 m/s (1300 mph)
zubka84 [21]

Answer:

= 3132.9 Joules

Explanation:

  • Kinetic energy is the energy possessed by a body when in motion.
  • Kinetic energy is calculated by the formula; K.E = 1/2 mV², where m is the mass of the body or object, and V is the velocity.
  • Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.

In this case;

Kinetic energy = 0.5 × 0.018 kg × 590²

                        <u>= 3132.9 Joules</u>

How can you minimize a collision summary
ElenaW [278]

One of the ways to minimize a collision is to slow down: When you can't find an escape and you're definitely going to collide with something, you should slow your vehicle down as much as possible.

Hope this helps ^^
