  2. Mae darn o secwin (sequin) yn pwyso 2.3 x 10-3 o gramau. Mae Donna wedi gwnïo 50 000 000 darn o secwin ar ei ffrog newydd. O wybod fod y ffrog wreiddiol yn pwyso 110g, cyfrifwch bwysau’r ffrog ar ôl iddi ychwanegu’r secwin? Rhowch eich ateb yn y ffurf safonol. Ysgrifennwch nifer y darnau secwin yn y ffurf safonol cyn cyfrifo’r pwysau. Newidiwch yn ôl i’r ffurf degol er mwyn adio pwysau’r ffrog gwreiddiol. Help llaw

  3. ATEB Màs: 2.3 x 10-3 Nifer: 5.0 x 107 Pwysau’r secwin: = 2.3 x 10-3 x 5.0 x 107 = 11.5 x 104 = 1.15 x 105 Pwysau gyda’r ffrog: 115000 + 110 = 115110 Ffurf Safonol: 1.1511 x 105 g
