What would be the resulting molarity of a solution made by dissolving 21.9 grams of kcl in enough water to make an 869-milliliter solution? show all of the work needed to solve this problem.

If 1.63 times 10 negative 4 of helium dissolves in 100.0g of water, what is the concentration in parts per million

Pls! plant cells and animal cells were observed under a microscope. the characteristics of two cells are listed below. cell p: does not capture sunlight cell q: has cytoplasm but no chloroplast which statement about the two cells is correct? cell q also has a cell wall. cell q also has large vacuole. cell p also has a large vacuole. cell p also has a cell membrane.

Amixture with the same composition throughout is!
