I hope this helps/answers your question! I vaguely remember getting this question before too
Answer:
S/.486 es el valor del anillo
Explanation:
Para hallar el precio del anillo se deben encontrar las moles de oro que contiene este.
Si el anillo es de 90g y solo el 59.1% contiene oro, la cantidad de oro en gramos es:
90g × 59.1% = 53.19g Oro en el anillo
Ahora, para convertir los gramos de oro a moles se debe usar la masa atómica del oro (197g/mol), así:
53.19g × (1mol / 197g) = <em><u>0.27 moles de oro contiene el anillo</u></em>.
Ya que cada mol de oro cuesta S/.1800, 0.27 moles de oro (Y por lo tanto, el anillo) costarán:
0.27mol × (S/.1800 / 1mol oro) =
<h3>S/.486 es el valor del anillo</h3>
Answer:
Germanium
Explanation:
The element Germanium is one with a relative molecular mass of 72. This corresponds to the mass number of this element.
Relative molecular mass of an element is the mass of a formula unit to that of a carbon-12 atom.
The chemical symbol of Germanium is Ge. It is a lustrous and hard metalloid belonging to the carbon group.
It was discovered by Clemens Alexander Winkler.
It would be carbon dioxide and water.
hope this helps you
