Which statement best explains how the solution
should be made?
Add 1.5 mL of 0,50 M H2SO4 to 10.5 mL of
water to get 12 mL of 4 M H2SO4
Add 1.5 mL of 4.00 M H2SO4 to 10.5 mL of
water to get 12 mL of 0.50 M H2SO4.
Add 1.5 mL of 4.00 M H2SO4 to 12 mL of
water to get 0.50 M H2SO4

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

i believe the answer is three water molecules

the answer is symmetrical : )

answer is: empirical formula is tl₂o. if we use 100 grams of compound, tha:

m(tl) = 96.2%  · 100 g ÷ 100%.

m(tl) = 96.2 g.

n(tl) = m(tl)  ÷ m(tl). n(tl) = 96.2 g  ÷ 204.4 g/mol.

n(tl) = 0.47 mol. m(o) = 3.77 g. n(o) = m(o)  ÷ m(o). n(o) = 3.77 g  ÷ 16 g/mol. n(ag) = 0.235 mol. n(tl) . n(o) = 0.47 mol : 0.235 mol /0.235. n(tl) . n(o) = 2 : 1.

m(tl₂o) = 204.4 g/mol  · 2 + 16 g/mol = 424.8 g/mol.

m(compound) = 456. 8 g/mol - 424.8 g/mol = 32 g/mol ( 2 oxygens); tl₂o₃.
