Answer:
we need a picture
Explanation:
but you can ask the question again with one
It would begin osmosis on it. If you put it in vinegar for example water would begin to seep through the membrane.
Answer:
70.1 mL
Explanation:
First let's look at the formula for magnesium nitrate, and get the molar mass, we should end up with Mg(NO3)2 for the formula and this should have a molar mass of 148.3 g/mol.
Lets get the number of moles of the magnesium by taking the number of grams over the molar mass, (21.94 g)/(148.3 g/mol). grams cancel and we're left with approximately 0.148 moles.
Now let's plug our numbers into the molarity formula, M = n/L, this should give us 2.11 mol/L = (0.148 mol)/L, now let's solve for L, divide both sides by 0.148 which will give us 14.26 L^-1 = 1/L now we take the inverse of both sides to get 0.07012 L = L.
Now we have the liters, but the question askes for milliliters, so let's multiply by 1000, and then after rounding to sig figs we will get 70.1 mL as our answer. (Note: I used the exact values instead of the approximations throughout this explanation, so if you calculate the answer by plugging in these values, it might be slightly off.)
Answer:
The least similar to a real gas found in the environment would be B.
Explanation:
Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.
