50g of water is placed into a beaker. the mass of the beaker is now 115g. what is the mass of the empty beaker?

Answer : The mass of the empty beaker is, 65 grams

Explanation : Given,

Initial mass of water = 50 g

Final mass of water = 115 g

Now we have to determine the mass of empty beaker.

Mass of empty beaker = Final mass of water - Initial mass of water

Mass of empty beaker = (115 - 50) grams

Mass of empty beaker = 65 grams

Therefore, the mass of the empty beaker is, 65 grams

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

16
