Bonjour, jai un devoir de chimie,qui est plus mathematique ducoup je le met dans la matiere "mathematique" merci a ceux qui m'aiderons.: 

 

complete en realisant les conversions:

.36,245hg = ..... g

.0,0000857 Mg= .... g

.24 kg = ... g

.332 mg =.... g

.458700mg =...g

.425,8 cg = ... g

.0,00658 kg =...g

.4200 ug (u= h(a lenver)) = ... mg

.57,84 dg = ...kg

.54,6 Gg = ... kg

 

Sagot :

complete en realisant les conversions:

.36,245hg = 3624,5 g

.0,0000857 Mg=85,7 g

.24 kg = 24000 g

.332 mg =0,332 g

.458700mg =458,7 g

.425,8 cg =4,258 g

.0,00658 kg =6,58 g

.4200 ug (u= h(a lenver)) = 0,00042 mg

.57,84 dg = 0,005784 kg

.54,6 Gg = 546000 kg

 

36,245hg = 3624,5 g

 

0,0000857 Mg=85,7 g

 

24 kg = 24000 g

 

332 mg =0,332 g

 

458700mg =458,7g

 

425,8 cg =4,258 g

 

0,00658 kg =6,58 g

 

4200 ug (u= h(a lenver)) = 0,00042 mg

 

57,84 dg = 0,005784 kg

 

54,6 Gg = 546000 kg

 

voilà......... :)
