How many moles of ammonia are in 0.175 L of 6.50 M aqueous ammonia solution? Find the numerical answer for this questions make sure to include the following : What is the chemical formula for ammonia? What is the formula for molarity ? When you give your numerical answer, what is the correct significant figures and how do you know that is the correct amount?

Moles of Ammonia (NH₃) in solution = 1.14

Given

0.175 L of 6.50 M aqueous ammonia

Required

moles of ammonia

Solution

Ammonia = NH₃

Molarity = moles of solute per liter of solution

n = M x V

n = 6.50 M x 0.175 L

n = 1.1375 moles

In a multiplication operation: the significant digits in the final product must follow the number of significant digits that are at least in the numbers involved in multiplying

6.50 = 3 sig fig

0.175 = 3 sig fig

So the result must be 3 sig fig

1.1375 rounded to 1.14

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
