C-12.thats all

Answer:

119,059.5 g/mol

Explanation:

First, find the mass of N2

On the periodic table, nitrogen is 14.007

Because there are two nitrogens, multiply it by 2

14.007*2 = 28.014 g

Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier)

4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol

Answer:

How to convert 1348 celsius to kelvin

Celsius and Kelvin are both units for temperature. The relationship between both units is given as;

Kelvin (K) = Celsius ( °C )  + 273

Inserting the values from the question;

Kelvin (K) = 1348 + 273 = 1621 K

Answer:

For example, 0.9% NaCl contains 0.9 g NaCl per 100 ml of solution or 9 g NaCl/l. This can be converted to molarity by dividing by molecular weight: 0.9% NaCl = (9g/l)/(58.5g/mole) = 0.15 M NaCl.

Answer:

0.058M is molarity of the solution

Explanation:

Molarity is defined as the ratio between the moles of solute (In this case, MgSO₄) and the liters of solution.

In the problem:

Moles MgSO₄: 0.32 moles

Liters solution: 5.5L

Molarity is:

0.32 moles / 5.5L =

0.058M is molarity of the solution

Answer:

An isochrone map in geography and urban planning is a map that depicts the area accessible from a point within a certain time threshold. An isochrone is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time".

Explanation:

Answer:

An isochrone (iso = equal, chrone = time) is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". In hydrology and transportation planning isochrone maps are commonly used to depict areas of equal travel time.

Velocity of a car while driving.

Explanation:

Answer:

In an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus. If there are more electrons than protons, the atom has a negative charge. If there are fewer electrons than protons, the atom has a positive charge.
