Butoxors [25]

Volume of the solution = 20.0 g NaCl * \frac{1 L solution}{10.0 g NaCl}

= 2 L solution x \frac{1000 mL}{1 L} =2000 mL

Volume of solute = 7.5 mL

Volume of water (solvent) = 2000 mL - 7.5 mL = 1992.5 mL water

NNADVOKAT [17]

Hey there!:

Isotopes :                          abundance :

46 Ti                                       8.0%

47 Ti                                        7.8 %

48 Ti                                      73.4 %

49 Ti                                       5.5 %

50 Ti                                         5.3 %

Weighted average =   ∑ Wa * % / 100

Therefore:

( 46 * 8.0) + (47 * 7.8 ) + (48 * 73.4 ) + ( 49 * 5.5 ) + ( 50*5.3 ) / 100 =

4792.3 / 100

= 47.923 a.m.u


       Hope that helps!
