What's ur fave MHA ship??

1.1 Kaminari x Jirou (KamiJirou)

1.2 Todoroki x Momo (TodoMomo)

1.3 Izuku x Ochako (IzuOcha)

1.4 Kirishima x Mina (KiriMina)

1.5 Tokoyami x Tsuyu (TokoTsuyu)

1.6 Tooru x Ojiro (OjiTooru)

1.7 Toga x Dabi (HimiDabi)

1.8 Bakugo x Uraraka (Kacchako)

I think is that :D

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)

explanation:

i think slash and
