Answer:
acid
Explanation:
im pretty sure because its then like a chemical reaction to the cabbage juice
Answer:
3.75 * 10^7 g of this water would have been consumed.
Explanation:
ppm represents parts per million.
ppm = (mass solute / mass solution ) *10^6
⇒It is a way to express the concentration of very dilute solutions.
For this situation we have:
ppm = (grams of mercury / grams of solution ) * 10^6
0.004 = (x grams of mercury / 1g of solution) 10^6
x = 0.004 /10^6
x = 4 *10^-9 g Mercury
This mass of mercury is per gram of solution. In the next step, we can calculate the amount of solution (water plus mercury) that would have to be ingested to ingest 0.150 g of mercury
0.150 g of Hg * (1g of solution/ 4 *10^-9 g Mercury)= 3.75 *10^7
3.75 * 10^7 g of this water would have been consumed.
Answer:
pH =3.45=-log [H3O+]
-3.45 log = [H3O+]
anti log -3.45 = 3.55 X10^-4
Explanation:
Answer:
The molarity of the solution is 1, 23 M.
Explanation:
We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)
Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g
58, 5 g-----1 mol NaCl
89,94 g ---------x= (89,94 g x 1 mol NaCl)/58, 5 g= 1,54 mol NaCl
1249 ml solution------ 1,54 mol NaCl
1000ml solution------x= (1000ml solutionx 1,54 mol NaCl)/1249 ml solution
x=1,23 mol NaCl---> The solution is 1, 23 molar (1,23 M)
