A glucose solution that is prepared for a patient should have a concentration of 180 g/L. A nurse has 18 g of glucose.

When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 20.4 g of carbon were burned in the presence of 66.2 g of oxygen, 11.8 g of oxygen remained unreacted. What mass of carbon dioxide was produced?

Bacteria and protists are primarily unicellular organisms. How do bacteria and unicellular protists differ? Options: A) Protists have a single chromosome in a nuclear region, but no nuclear membrane.

A solution contains 0.159 mol K3PO4 and 0.941 molH2O. Calculate the vapor pressure of the solution at 55 ∘C. The vapor pressure of pure water at 55 ∘C is 118.1 torr. (Assume that the solute completely dissociates.)

When 711 J of heat is added to a 41.1 g of an unknown metal, the temperature of the metal increases from 22oC to 94oC. Calculate the specific heat of this metal
