Answer:Beryllium iodide has a molar mass of 262.821 g mol−1 , which means that 1 mole of beryllium iodide has a mass of 262.821 g . To find the mass of 0.02 moles of beryllium iodide, simply multiply the number of moles by the molar mass in conversion factor form.
Explanation:
Answer:
3. An oxygen atom with 8 electrons, 8 protons, and 9 neutrons .
Explanation:
if an atom contains equal numbers of protons and electrons, the atom is described as being neutral.
Heat = mC(t2 - t1)
So, 2510 j = 0.158kg
1000g/1kg * C * 61.0 - 32degrees C
therefore, C = 0.5478 j/g degrees C
