The concentration of lead nitrate is 3.48 M.
<u>Explanation:</u>
The molarity can be found by dividing moles of sucrose by its volume in litres. We can find the number of moles of sucrose by dividing the given mass by its molar mass. Now we can find the moles as,
Here mass of Pb(NO₃)₂ is 380 g
Molar mass of Pb(NO₃)₂ is 331.2 g/mol
Number of moles = 
= 
= 1.15 moles
Volume in Litres = 330 ml = 0.33 L
Molarity = 
= 3.48 mol/L or 3.48 M
So the concentration of lead nitrate is 3.48 M.
Answer:
Hey there,
Your answer is iii. Brown cows produce white milk. (1 point) <u>and</u> ii. Brown cows never produce chocolate milk. (1 point)
You already know from the basic understanding that chocolate comes from beans, not cows, and is added to milk, and thereby- brown cows do not produce chocolate milk. You also know that they produce white milk.

Answer:
An asexually reproducing organism would have the best chance of repopulating the world.
Explanation:
Sexual reproduction is a method of reproduction that involves two parents and the formation and subsequent fusion of male and female gametes during fertilization. On the other hand, In asexual reproduction, only one parent is involved and produces offspring by making copies of itself through various methods such as binary fusion, budding and vegetatively.
In a case of a catastrophic event that wiped out almost all organisms, an organism that reproduces asexually have a greater chance of repopulating the world because of the following advantages in reproducing asexually:
1. Only one parent is needed, therefore reproduction is easier.
2. It isaves time and energy. Since almost all organisms have been wiped out, there is a lesser likelihood of finding a compatible mate, so reproducing asexually will give the organism a better chance.
3. It occurs at a very fast rate; much faster than sexual reproduction
4. The population can increase very quickly and colonization of new habitats is much easier.
All these advantages will give the esexually reproducig organism a fairer chance to repopulate the world.
