Respuesta:
4.42 × 10⁻⁶ m³
Explicación:
Paso 1: Información provista
- Densidad del osmio (ρ): 22600 kg/m³
Paso 2: Convertir 100 g a kilogramos
Usaremos el factor de conversion 1 kg = 1000 g.
100 g × 1 kg/1000 g = 0.100 kg
Paso 3: Calcular el volumen ocupado por 0.100 kg de osmio
La densidad es una propiedad intensiva, igual al cociente entre la masa y el volumen.
ρ = m/V
V = m/ρ
V = 0.100 kg / (22600 kg/m³) = 4.42 × 10⁻⁶ m³

Explanation:
We have the following chemical reaction:
Ag₂O → Ag + O₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
2 Ag₂O → 4 Ag + O₂

Answer:
6.33 years
Explanation:
In this question, we determine the NPER or the time period that is shown in the attached spreadsheet
Given that,
Present value = (9% × $1,000) ÷ (8.75%) = $1,028.57
Assuming figure Future value = $1,000
Rate of interest = 8.4%
PMT = $1,000 × 9% = $90
The formula is shown below:
= NPER(Rate;PMT;-PV;FV;type)
The present value come in negative
So, after solving this, the answer would be 6.33 years
