A sample has x grams of salt. What is this amount in kilograms (or another SI unit)?
A sample has x grams of salt. What is this amount in kilograms (or another SI unit)?
How many grams are needed to make x mL of an x M solution?
A molar mass is given. Determine the osmotic pressure in mm Hg for a sample at x °C, x grams and x mL.
The volume (mL) and temperature (°C) for a sample of benzene are given along with its melting point, density, specific heat and fusion enthalpy. How much energy is transferred in J?
What is the longest wavelength (in nm) that can create x kJ/mol of energy?
Two part question. First calculate the energy when given frequency. Then calculate energy when given wavelength in nm.
Choose all that apply. A liquid’s vapor pressure (in mmHg)at a temperature (K) is given. The compound is placed in a container (mL) and put at a certain pressure (mmHg). If the container is reduced to a new mL, what happens?
Four elements are given. Arrange them from smallest to largest atomic radius using the periodic table trends.
Rank the given substances from highest to lowest boiling OR melting point. This solver works for both. You are given molality and formulas for four compounds.
Four elements are given. Arrange them from lowest to highest ionization energy using the periodic table trends.
