Question

N = 1.8 × 10P2O3M(P2O3) - ? n - ?m -?​

Answer 1

Ответ:

Объяснение:

M(P2O3) = 31*2 + 16*3 =110 г/моль

n(P2O3) = N / Na = 1,8 *10²³ / 6 *10 ²³ = 0,3 моль

m(P2O5) = n * M = 0,3 * 110 = 33 г

Answer 2

It seems like you've provided a mathematical expression with variables and placeholders, but it's not clear what you're asking for. The expression you provided is:

$N = 1.8 \times 10^{P_2O_3M} (P_2O_3) - ?n - ?m - ?$

Here, $N$ is equal to $1.8 \times 10^{P_2O_3M} \times (P_2O_3)$ minus some unknown values represented by $?n$, $?m$, and $?$. If you have specific values for $P_2O_3M$, $P_2O_3$, $?n$, $?m$, and $?$ that you would like to substitute into the equation, please provide those values, and I can help you calculate $N$. Alternatively, if you have a different question or if there's a specific calculation you need assistance with, please let me know!
