0.283 M solution X 176.12 g = 50 g/L

how many g per 30 mL?

150?

176.12 g/ mol I meant to write

uhh whoah not 150 lol I calculated 1.67g per 30 mLs, but i'd like some verification :)

I don't believe any of those numbers.

First, I obtained 49.8 for the first instead of 50 g/L. You are allowed 3 significant figures; why not use all of them?
Then 49.8 g/L x 30/1000 = ?

To find the answer to this question, we first need to understand the given information.

From the given data, we know that a solution with a concentration of 0.283 M (moles per liter) is mixed with 176.12 grams of a substance. Additionally, it is mentioned that the concentration of this solution is 50 g/L (grams per liter).

Now, we need to find out how many grams are present in 30 mL (milliliters) of this solution.

To do this, we'll use a conversion factor. We know that the concentration of the solution is 50 g/L, which means that every liter of the solution contains 50 grams of the substance.

Since we want to find the number of grams in 30 mL, we need to convert the volume from mL to liters. There are 1000 mL in one liter, so we can set up the following conversion factor:

1 L / 1000 mL

Now, we multiply this conversion factor by the given concentration of 50 g/L.

(1 L / 1000 mL) * 50 g/L = 0.05 g/mL

Therefore, there are 0.05 grams of the substance in 1 mL of the solution.

To find out how many grams are in 30 mL, we can simply multiply the conversion factor we found (0.05 g/mL) by 30 mL.

0.05 g/mL * 30 mL = 1.5 grams.

Therefore, there are 1.5 grams in 30 mL of the solution.
