What is the molarity of a solution that contains 25 g of HCl in 150 mL of solution??
Stels [109]
To find molarity 
1) number of mol of solute.
Solute is HCl.
M(HCl)= 1.0+35.5 =36.5 g/mol

25g *1 mol/36.5 g = 25/36.5 mol HCl

2) Molarity is number of mole of the solute in 1 L solution.
150 mL = 0.150 L

(25/36.5 mol HCl )/(0.150 L) = 25/(36.5*0.150) ≈ 4.57≈4.6 mol/L

A liquid with high viscosity _____ flow easily and _____ effective in wetting a surface.
scoundrel [369]

A liquid with high  viscosity does not flow easily and is not effective in wetting a surface.

When a metal is subjected to corrosive elements including salt, moisture, and high temperatures, a reaction called corrosion takes place inside the metal. Some foods contain metallic compounds that can corrode a material. The majority of corrosion is simply surface dis-colouration, which polishing agents may quickly remove.

Increasing viscosity and constant intermolecular water bonding together result in surface tension. Any liquid that was more viscous than water possessed a surface tension that was equal to or lower than that of water. Viscosity with surface tension decrease when temperature rises.

Therefore, a liquid with high viscosity does not flow easily and is not effective in wetting a surface.

Does the color of bell peppers effect the number of seeds inside? Please someone help ASAP I need it today
Mekhanik [1.2K]

I don't think so. "It's not a matter of pigment discrimination: Red and yellow bell peppers are essentially just green peppers that have been allowed to ripen"
