3/3 Challenge!!!1 for chem. wiz only!?

B. Add the following MASSES and express the answer in GRAMS:
45.00 g, 1.0000 kg, 375 mg, 22.0 dg, 88 cg = ???

Answer:
1.0000 Kg = 1000.0000 g
375 mg = 0.375 g
22.0 dg = 2.20 g
88 cg = 0.88 g
45.00 + 1000.0000 + 0.375 + 2.20 + 0.88 + = 1.05 x10^3 g
Look at significant figures
put all in grams

1.000kg =1000g
375mg = 0.375g
22dg = 2.2g
88 cg = 0.88g

So 1000+0.375+2.2+0.88=1003.455g
0.066
answers above are true but u should learn how to calculate i am sending u a link that u can find the conversions for SI mass units
