I really need help with #3 1. Determine the mass of four 100mL volumetric flasks.

2. In each flask prepare one of the following sucrose solutions: 0.0625M, 0.125M, 0.250M, and 0.500M.

3. Determine the mass of each solution then calculate the density of each solution.

*is there a formula I’m supposed to use? I don’t understand anything and this is due at 11:59pm

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

can you list the answers so i can answer
