I need help I don’t undertsand how to convert moles into grams

1. a. For a reaction that follows the trend 1/[A]t = kt + 1/[A]0, a graph of 1/[A]t on the y-axis versus t on the x-axis will have what slope? b. For a reaction that follows the trend...

1. The data below is for the reaction of NO(g) from automobiles reacting with O2(g) in the atmosphere to produce NO2(g) which is a component of smog. Experiment [NO] (M) [O2] (M) Initial...

1. Find the overall reaction of these three steps: IBr(g) -> I(g) + Br(g) IBr(g) + Br(g) -> I(g) + Br2(g) I(g) + I(g) -> I2(g)

Does increasing or decreasing volume change the moles in a solution, or does that just affect the concentration? If I have 0.035711 moles in 100mL and I'm asked how many moles in 5mL...

we in class got this answer for this problem 4.21*10^24 atoms but I don’t know how to solve it or how my teacher got the answer.

THANKSSS PLS reply asap

how to solve it

Na2CO3 reacts with Ca(OH)2, and forms CaCO3 and NaOH. After seperating and heating CaCO3, it decomposes and CaO and CO2 are produced a) write balanced equations b)If...

I honestly have no clue where to start and I need a lot of help.

Stoichiometry

A. 0.50M acetic acid B. 0.050M acetic acid C. 0.050M acetic acid D. Use Le Chatlier's principle to explain why percent dissociation increases as the concentration...

What does the superscript 0 mean? The question asks for the electron configuration of Cr0 I know if its plus or minus you subtract or add electrons based on that number but...

Average volume of CO2 in the experiment was 37.68mL. water temp 20.08 C vapour pressure of water 17.7 mmHg Barometric pressure 758.3mmHg P1V1/T1 = P2V2/T2 I...

concentrated hydrochloric acid and 20.0 mL concentrated nitric acid to 300 mL water. More water is added until the final volume is 1.00 L. Calculate [H+], [OH-], and the pH for this solution....

Not sure how to do it. Ammonia gas is made by N2 + 3 H2 = 2 NH3

The pH at the equivalence point when a 0.20 M weak base (Ka = 9.1 x 10-7) is titrated with a 0.20 M strong acid is?

and Using the same equation (and 9 chlorine molecules) as above, how many Iron (III) chloride (FeCl3) molecules can I create?

Is this question true or false?
